Fairbanks, Alaska (UAF) – A scientific team led by University of Alaska Fairbanks researchers has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas.

The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.

“We are looking at humans as ecologists do, as biologists do,” said Ben Potter, a UAF anthropology professor and co-lead author of the paper. “Even very early on, they are able to adapt to changing conditions.”

The study, published recently in the journal Science Advances, shows that people living between 13,000 and 11,500 years ago in what is now Interior Alaska relied on freshwater fish like burbot, whitefish, and pike for food.

The study builds on earlier UAF findings that documented salmon fishing by the same population of ancient humans.

“That discovery was really surprising because it was far from the ocean, in an area near the edge of salmon habitat,” said Potter. “That started us thinking: This could be a whole other angle on human ecology beyond large mammal hunting.”

This new study began with a comprehensive review of all Interior Alaska archaeological sites 7,000 years old and older.

The scientists found fish bones at seven sites.

The team of archaeologists, anthropologists, and fisheries biologists analyzed the bones to determine their age and species.

The bones were found inside homes and hearths and tended to be associated with base camps, rather than short-term hunting camps.

They also were far from lakes and streams, so it’s unlikely that predators moved them.

The absence of fishhooks or spears at the sites suggests that the early Alaskans likely used nets and perhaps weirs to harvest the fish.

“This is a compelling, evidence-based case for freshwater fishing at the end of the last Ice Age,” Potter said.

Recent large-scale excavations of residential base camps in the Tanana River basin have offered scientists a new opportunity to study early human populations in the region, he said. “This is a first in the Americas because, up until the last few decades, we haven’t had fish remains clearly associated with human activities in these very early sites.”

Scientists have documented humans in Alaska as far back as about 14,000 years ago.

The heaviest use of freshwater fish by those early Alaskans appears to be between 13,000 and 11,500 years ago during the Younger Dryas, a period with cold and dry conditions in the midst of an overall warming trend at the end of the last ice age.

Until the beginning of the Younger Dryas, people relied more on waterfowl to augment large game like bison and elk.

When temperatures started dropping around 13,000 years ago, that changed.

Bones found at archaeological sites indicate they began to exploit multiple species of freshwater fish.

“While we don’t know why the use of waterfowl diminished, we know that the climate was changing,” Potter said. “One of the ways the people were able to adapt is to incorporate these new species and new technologies. Burbot, in particular, can be caught in late winter and early spring, when food resources were most scarce.”

The solid tie to modern subsistence activities is also compelling, he said.

“There are millennia and millennia of fish use that continues into the modern day. Indigenous people’s ancestors thousands of years ago were using the same resources. That has meaning to people today’,’ he said.

OPINION: CDQ program and pollock fishery are essential to Western Alaska

OPINION: CDQ program and pollock fishery are essential to Western Alaska


By Eric Deakin, Ragnar Alstrom and Michael Link

Updated: 1 hour ago Published: 1 hour ago

We work every day to support Alaska’s rural communities through the Community Development Quota (CDQ) program and have seen firsthand the lifeline the program provides to our state’s most isolated and economically vulnerable areas.

This program is one of the most successful social justice programs in the United States, giving rural, coastal communities a stake in the success of the Bering Sea fisheries, and transferring these benefits into community investments. Our fisheries participation provides $80 million to $100 million of programs, wages and benefits into Western Alaska annually, and the full economic reach of the CDQ program is substantially larger when accounting for jobs and support services statewide.

In some communities, CDQs are the largest and only private-sector employer; the only market for small-boat fishermen; the only nonfederal funding available for critical infrastructure projects; and an essential program provider for local subsistence and commercial fishing access. There is no replacement for the CDQ program, and harm to it would come at a severe cost. As one resident framed it, CDQ is to Western Alaska communities, what oil is to Alaska.

Consistent with their statutory mandate, CDQ groups have increased their fisheries investments, and their 65 member communities are now major players in the Bering Sea. The foundation of the program is the Bering Sea pollock fishery, 30% of which is owned by CDQ groups. We invest in pollock because it remains one of the most sustainably managed fisheries in the world, backed by rigorous science, with independent observers on every vessel, ensuring that bycatch is carefully monitored and minimized.

We also invest in pollock because the industry is committed to constantly improving and responding to new challenges. We understand the impact that salmon collapses are having on culture and food security in Western Alaska communities. Working with industry partners, we have reduced chinook bycatch to historically low levels and achieved more than an 80% reduction in chum bycatch over the past three years. This is a clear demonstration that CDQ groups and industry are taking the dire salmon situation seriously, despite science that shows bycatch reductions will have very minimal, if any, positive impact on subsistence access.

The effects of recent warm summers on the Bering Sea ecosystem have been well documented by science. This has caused some species to prosper, like sablefish and Bristol Bay sockeye salmon, while others have been negatively impacted, including several species of crab and salmon. Adding to these challenges is the unregulated and growing hatchery production of chum salmon in Russia and Asia, which is competing for limited resources in the Bering Sea, and increasing management challenges.

Attributing the current salmon crises to this fishery is misguided and could cause unnecessary harm to CDQ communities. Without the pollock fishery, we would see dramatic increases in the cost of food, fuel and other goods that are shipped to rural Alaska. We would also see the collapse of the CDQ program and all that it provides, including a wide array of projects and jobs that help keep families fed and children in school.

The challenges Alaska faces are significant, and to address them we need to collectively work together to mitigate the impacts of warming oceans on our fisheries, build resiliency in our communities and fishery management, and continue to improve practices to minimize fishing impacts. We must also recognize the vital need for the types of community investments and job opportunities that the CDQ program creates for Western Alaska and ensure these benefits are considered when talking about the Bering Sea pollock fishery.

‘Drag racing for dogs:’ Anchorage canines gather for the ‘Great Alaska Barkout’


ANCHORAGE, Alaska (KTUU) – Alaska’s first “flyball” league held its annual “Great Alaska Barkout Flyball Tournament” on Saturday in midtown at Alyeska Canine Trainers.

Flyball is a fast-paced sport in which relay teams of four dogs and their handlers compete to cross the finish line first while carrying a tennis ball launched from a spring loaded box. Saturday’s tournament was one of several throughout the year held by “Dogs Gone Wild,” which started in 2004 as Alaska’s first flyball league.

“We have here in Alaska, we’ve got, I think it’s about 6 tournaments per year,” said competitor and handler Maija Doggett. “So you know every other month or so there will be a tournament hosted. Most of them are hosted right here at Alyeska Canine Trainers.”

State of Alaska will defend its right to facilitate oil and gas development


Last week, Superior Court Judge Andrew Guidi indicated he will rule that Alaska does not have authority to permit access across its lands to facilitate oil and gas development on the North Slope.

The Alaska Dept. of Natural Resources plans to fight and appeal any final adverse ruling that undermines the state’s constitutional interests in resource development.

The Department of Natural Resources has issued a permit allowing Oil Search Alaska (OSA) to cross the Kuparuk River Unit, operated by Conoco Phillips Alaska, to develop the Pikka Unit. As described in the State’s brief to the court, “the denial of such access implicates the delay of development of millions of barrels of oil and billions of dollars of public revenues.”

“The State of Alaska has a constitutional obligation to maximize the development of our resources,” DNR Commissioner John Boyle said on Nov. 22. “We have to confirm with the Supreme Court that we have the authority to permit access for all developers to ensure we can meet this obligation.”

Once the Superior Court issues the final judgement, Alaska will be able to file its appeal. This is expected to occur in the coming weeks.
